AUTOMATIC FEEDING AND WlCl =RAlSING LAMP.

EBPI-JCIPICATION forming part of Letters Patent No. 311,972, datedFebruary 10, 1885.

Applirntion filed February 15, 1884. (No model.)

To ctZZ whom it may concern.-

Be it known that I, Ti-rorms A. Frrzsmron's, of the city and county ofSan Francisco. and State of California, have invented an Improvement inSelfFeeding Lamps and Clock Attachments for Feeding the Wick; and Ihereby declare the following to be a full, clear, and exact descriptionthereof.

My invention relates to a new and useful selffeeding lamp and clockattachment for feeding the wick; and it consists in an oil-reservoirfrom which is suspended, by an air and an oil pipe, a peculiar cupcontaining the burner mechanism, to the wick of which a feeding deviceisapplied, to which motion is transmitted to feed the wick by suitablegearing connected with a clock suspended from the cup, as I shallhereinafter fully describe.

The connection of the oil-reservoir, cnp,and clock, the shape of saidcup, the arrangement of the wick, the construction of the feedingdevice,and the arrangement of gearing by which the power is transmittedfrom the clock, and other details, all form part of and are included inmy invention, as I shall hereinafter particularly point out.

The object of my invention is to provide a lamp capable of burning aconsiderable time without attention by reason of the automatic feedingof the oil and wick, and therefore particularly adapted for use inchurches as a sanctuary-lamp, the light of which is not intended to beextinguished. The further object is to provide in a practical manner fora combined lamp and timepiece, whereby the functions of both may beexercised and their uses enjoyed together.

Referring to the accompanying drawings, Figure l is a perspective View.Fig. 2 is a side elevation of the wick-feeding device and gear-wheels.Fig. 3 is a transverse section. Fig. 4c is a detail to be referred to.

A is the main receptacle or reservoir for V oil, and it may be of anydesired shape in general outline and cross-section,and suitablyornamented. The shape which I prefer is that shown as giving thegreatest interior capacity with the least outside dimensions. This isprovided with a feed-aperture, a, covered by an air-tight cap, a. Intoone side of this oilreservoir is let a tube, 13, the top of .which opensclose under the cap a at an elevation above whatever level of oil maybein the reservoir. Into the opposite side of the reservoir is let atube, 13, opening on the inside near its bottom. These tubes extend downwardly and open into opposite sides of the cup 0, and support said cup.The tube B is for air, and the tube 13 is for oil, the self feedingoperation from the upper reservoir being thus periodical, as the end ofthe air-tube is exposed or covered by the receding or augmenting of theoil in the cup 0. The peculiar shape of this cup is a novel feature inthis connection. Its bottom or lower portion, from a point about onaline with the air-tube, is very much narrowed, receding rapidly, asshown. Its upper portion is widened out, and it is provided with agallery or shelf, 0, and an encircling flange, c. The object of thisshape is to provide increased capacity on a line with and above theentrance of the air-tube, in order that a large supply of oil may be fedand contained at and above that level, the period of consumption ofwhich will be considerable, while just below the line of theair-entrance, the capacity being materially reduced, the consumptionwill take place rapidly, and there fore will hasten the self-feedingoperation by uncovering completely the air-entrance, and thus preventthe exposure of too great a portion of the wick. The shelf 0 promotesthis result and acts as an overflow-bed, and the flange c is a guard toprevent the spilling of any oil by the accidental tipping of the cup.

Over the end of the oil-tube B, I have a cut-off slide, 1), though avalve of any other deseription would answer.

Standing within the cup 0 is a light frame, D, from which an arm, (1,extends upwardly, and carries the slotted burner-plate l3, through whichthe wick F projects. The wick is rolled on a reel, G, on one of thetubes B B, and thence extends downward over a gutter-way, g, to catchthe drippings, and under a guideroller, 9, to and under a guide-roller,d, on

arm (I, and up through the burner-plate, as shown.

H is the globe fitted over the cup.

I is a clock of suitable description, the dialplate of which is in fullview. This clock is suspended from the cup 0 by means of arms roo .6from the cup, secured to the clock by means of screws 6.

In Fig. 2, J is the shaft which carries the hour-hand of the clock. Itsgear J meshes with a pinion, k, on a shaft, K, above, and which alsocarries a pinion, 7a. This pinion meshes with a large gear, L, whichmeshes with a gear, M, on a shaft, m, mounted over the edge of cup 0.This shaft carriesa-pinion, N, which meshes with a gear, 0, on a shaft,0, mounted within the cup in the top of frame D. This shaft carriesafeed-pinion, P, which operates against the wick, said wick being heldin contact with it by means of a roller, 1), on the other side. By thismechanism the power of the clock is transmitted up to, over, and downinto the cup, and feeds the wick constantly as it is consumed. Theamount of this feed is a matter of calculation, and is determined by thecharacter and number of the intervening gears.

With the clock I have used I have found it necessary to reduce themotion by the interposition of the large gear L; but from the gear M itwill be observed that the times of revolutions of each of the succeedinggears are equal, and therefore I am enabled to indicate on said gear theamount of feed which the wick has undergone. This I accomplish by aplate, Q, (shown in Figs. 2 and 4,) acting as a face for said gear M,the plate being properly graduated.

On the shaft which carries gear M is a dial.- finger, g, which movesover the graduated plate Q, for the purpose referred to.

Any proper face-plate may be used to conceal the gears, and the wholedevice may be suitably ornamented.

By removing the small screw which holds the frame in which the plate Q,gear M, and its shaft are contained, these parts may be removed and thelamp and clock thrown out of engagement and each perform its functionseparately, and, if desired, the clock itself may be removed by takingout screws 6.

I am aware that clocks and lamps have been heretofore combined in thesame frame-work, each having its own function, and I do not, therefore,claim such, broadly.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is

1. In a lamp having an oil-reservoir from which an air tube or passageand an oil tube or passage open out separately, a cup containing theburner devices, and into which the said air-tube and oil-tube open toaccomplish the automatic feed of the oil thereto as the mouth of theair-tube is covered or uncovered by theoil, as described, said cuphaving a wide upper portion beginning about on a line with the mouth ofthe air-tube, and a lower portion rapidly contracting or narrowing whereit joins the wide upper portion, substantially as and for the purposeherein described.

In witness whereof I have hereunto set my hand.
